This paper considers the probability of power supply failures at bulk water distribution pump stations. Electrical power supply is important within the bulk water distribution environment, particularly when pumping is required. Reliability of power supply is commonly expressed by means of indices, such as amongst others, the SAIDI and SAIFI indices as defined by the Institute of Electrical and Electronics Engineering (IEEE). These indices are used to calculate the probability of failure associated with power supply. Data was obtained from a number of sources and used to benchmark the reliability of South African power supply against that of other countries. The reliability of power supply from seven South African Water Board (Rand Water) pump stations is also analysed. Limited data seems to be available that allows one to quantify the reliability of pump systems, taking into account the reliability of the various system components.

Groundwater is a strategic water resource in rural Limpopo Province and it accounts for almost 70% of rural domestic water supply. The resource is available throughout the Province in varying quantities and qualities depending on the hydrogeological properties of the underlying aquifer. These properties are mostly secondary in nature and are constrained by the processes of weathering, faulting, fracturing and the influence of intrusive rocks. These properties define typical fractured aquifers in which the selection of drilling sites requires a thorough scientific approach to locate a successful productive borehole. While most water service authorities in the Province have been randomly developing new boreholes with limited success rates, the analysis of datasets in the newly established groundwater data repository, the Limpopo Groundwater Resource Information Project (GRIP) demonstrates that large quantities of groundwater can be obtained and used for bulk supply if the drilling sites are scientifically selected. The GRIP dataset contains 24 922 entries of which 4 000 were tested. The pumping test results indicate that an estimated 576 000 m3/d (210 Mm3/a) can be sustainably abstracted from boreholes in approximately 2 500 villages that are dispersed throughout the Province. However, more than 50% of these boreholes are unequipped of which 3 000 can provide a combined yield of 109 Mm3/a based on a 24 h abstraction rate. These results show that groundwater can be developed as a potential viable bulk-water supply source. This paper attempts to demonstrate, using the existing GRIP dataset, that groundwater is an underutilised resource that can be viably and cost-effectively developed as an alternative bulk water source or conjunctively with surface water.

Since the introduction of the Water Law in 2004, national river basin management in Indonesia has been carried out by 30 public river basin management organizations (RBOs), called either Balai Besar Wilayah Sungai(s) (BBWSs) or Balai Wilayah Sungai(s) (BWSs); the two are referenced together here as B(B)WSs. These national government agencies fill both regulatory and management functions, as well as undertaking construction, operation, and maintenance of river infrastructure and irrigation systems larger than 3,000 hectares. Provincial water agencies also provide water resource and river basin management in provincial basins and basins of national river territories, in coordination with the national river basin agencies.

Successful mid-sized cities will be vital to India’s growth and prosperity in the coming decades. Indian cities are home to over 375 million people now, and their population is likely to double by 2035. Yet water supply in most mid-sized cities falls short of Government of India benchmarks for service, efficiency and cost recovery. In many of them water flows in the pipes for 2 hours a day or less, its quality is poor, and it is provided by utilities that cannot even cover their operating costs. Following a brief introduction to the three city case studies (section two), the report lays out the Indian water sector’s unique challenges, and using case examples to substantiate findings (section three). The challenges include day-to-day operational issues associated with running a utility, as well as policy and planning issues that affect the utility’s governance and investment planning to meet current and future demand. The results of a financial viability gap analysis, applied to Bhubaneswar and Coimbatore reveal the magnitude of improvements required, and the key drivers that affect the utilities’ financial performance (section four). These complex challenges make traditional PPP models, Management Contracts, Concessions and Leases, less amenable for use in mid-size Indian cities. As section five describes, this is because the traditional models are too risky for the operator or government or too limited in scope to create lasting improvements. The remaining sections focus on explaining the design and procurement strategy for the two innovative PPP models, the phased performance based contract and the Joint Venture (JV) Partnership (section six and seven). These models have the potential to deliver better results than the traditional PPPs and business as usual scenarios. This is because in addition to reforming dysfunctional utilities into focused and accountable organizations, they are able to respond to information uncertainty, include strong incentives, have clear sources of funding, and promote capital efficiency.

Water supply and sewage (WSS) operations in Ludhiana resemble that of many Indian cities; service levels are poor when compared to benchmarks; cost recovery is low; the municipal corporation subsidises operating deficits; the Government finances capital expenditure; assets are created through a State owned entity; internal capacity, systems and procedures are weak. The State Government has taken a decision to make key municipal corporations (including Ludhiana) responsible for future asset creation and also expects them to share capital expenditure. To improve the quality of service, the city needs immediate capital investments and change in management practices. Key institutional actions to achieve this are a) WSS operations focusing on higher cost recovery, b) increased contribution from the municipal corporation to WSS capital expenditure financing as opposed to O & M financing and c) modern governance structure for WSS operations.

Kosovo is a small and young state that gained an interim United Nations (UN)-administered status in the wake of the Dayton peace accord only in 1999; it declared independence in 2008. Compared to neighboring countries, it is still lacking in its basic infrastructure and its administrative and technical skills. In addition, with the onset of the War in Yugoslavia in 1992 most investment and normal maintenance came to a standstill. Much of the publicly owned infrastructure fell into disrepair or was vandalized, but private investments led to a construction boom which, however, is leading to many environmental problems. The government is committed to reconstruction and to the development of a peaceful state. It also intends to align with EU policies. Thus, the study has the specific objectives to: (i) assist the government to improve its river basin planning and management by providing (for demonstration purposes) a replicable tool and simulation model for integrated river basin planning and management; and (ii) support the government in its identification of priority measures of structural and non-structural nature to help strengthen the water resources sector performance. The source(s) for the financing of the identified projects will need to be identified further by the Government as the World Bank has not committed to involvement in the sector.

Water, as a resource, is integral to human activities of all kinds. The water sector, as a society's means of ensuring individuals have sufficient water is fundamental to recovery and development. While designing and implementing water supply operations in any societal context is a complicated endeavor, doing so in contexts affected by conflict, fragility and violence is inherently associated with compounded challenges. The objective of this study is to summarize operational lessons from task teams to inform effective water supply and access operations in conflict-affected and fragile situations. This paper defines common operational challenges and describes actions that task teams have taken in Bank projects in order to address those challenges. Further, the paper explores ways to ensure that water supply projects in fragile and conflict-affected situations (FCS) contexts, in addition to achieving technical objectives, can also address perpetual causes of conflict and fragility. The risks of escalating violence and decreasing stability are exacerbated in situations where access to water resources and services is poor, constrained, inequitable, and unsustainable. This knowledge product summarizes lessons from World Bank task teams that have prepared and implemented water supply projects in locations affected by conflict, fragility and violence. The findings intend to support operational problem-solving during water operations that are conducted in these situations. The study engaged task team members and surveyed project documentation, consolidating data on contextual and operational challenges and responsive methods that staff recommend. The findings of this study show that clear priorities in process and organizational capacity, with a focus on access, are needed to ensure that water supply operations in FCS contexts are conflict-sensitive.

Over the past 25 years, Uganda has experienced sustained economic growth, supported by a prudent macroeconomic framework and propelled by consistent policy reforms. Annual Gross Domestic Product (GDP) growth averaged 7.4 percent in the 2000s, compared with 6.5 in the 1990s. Economic growth has enabled substantial poverty reduction, with the proportion of people living in poverty more than halving from 56 percent in the 1992 to 23.3 percent in 2009. However, welfare improvements have not been shared equally; there is increasing urban rural inequality and inequality between regions. Revitalizing economic growth and tackling persistent poverty will require addressing a number of challenges. These include alleviating infrastructure bottlenecks; increasing agricultural productivity; managing land, water and other natural resources; addressing demographic challenges; and confronting governance issues. The development and management of water resources is intimately linked to Uganda's continued development ambitions. Water can be both a positive force-providing productive input to agriculture, industry, energy and tourism, and sustaining human and environmental health-as well as a destructive one-to which the devastating consequences of floods and droughts can attest. The National Water Resources Assessment (NWRA) estimates that Uganda's total renewable water resources are about 43 million cubic meters (MCM), less than was estimated in the Ministry of Water and Environment's (MWE's) Sector Investment Plan (SIP) in 2009. About 13 percent of this is sustainable groundwater (5.67 MCM) and the balance is surface water (37.41 MCM). About one half of all districts in Uganda experience annual rainfall deficits-the difference between evapotranspiration and rainfall-ranging from slightly above zero to 400 mm. The frequency of rainfall anomalies below normal (or long-term annual average) is significantly greater than the frequency of rainfall anomalies higher than normal. The Uganda water Country Assistance Strategy (CAS) aims to assist the Government of Uganda (GoU) in identifying priority actions for building on successful outcomes, tackling remaining challenges, and exploiting opportunities in Uganda's water sector. The objective of the water CAS is to define the World Bank's strategic role in supporting GoU to better manage and develop its water resources. The recommendations of the water CAS are complementary to the World Bank Uganda Country Assistance Strategy (CAS) 2011-15 priorities for Uganda and consistent with the country's development objectives as defined in the National Development Plan (NDP) and water and related sector plans and strategies, which form the foundation of the World Bank Uganda CAS.
